4164c39a4a machine/nrf: do not compare slices against nil 
Comparing slices against nil currently causes the slice to escape, due
to a limitation in LLVM 8. This leads to lots of unnecessary heap
allocations. With LLVM 9 and some modifications to TinyGo, this should
be fixed. However, this commit is an easy win right now.

Returning an error when both slices are nil is not necessary, when the
check is left out it should just do nothing.

For updating an SPI screen using the st7735 driver, this results in a
~7% performance win.

d266e44bc5 machine/samd21: use pins specified in I2CConfig 
Instead of configuring machine.I2C0, machine.I2C1, etc. statically,
allow the pins to be set using machine.I2CConfig. This will also
automatically configure the correct pin mode for each pin instead of
having to specify that manually.

d2856bd6bd nrf: improve SPI write-only speed, by making use of double buffering 
The SPI peripheral in the nrf chips support double buffering, which
makes it possible to keep sending continuously. This change introduces
double buffering on the nrf chips, which should improve SPI performance.

Tested on the pca10040 (nrf52832).

9d35c1197f machine/stm32f103xx/nucleo-f103rb: add support for NUCLEO-F103RB STM32F1-based board 
Compared to the already supported stm32f103xx "bluepill" board this:

- features 128 KiB flash memory size ("RB" suffix) instead of 64 KiB, see `targets/stm32f103rb.ld`
- has onboard ST-LINK/V2-1 programmer and debugger requiring different OpenOCD configuration file
- uses USART2 connected to ST-LINK/V2-1 debugger as virtual COM port over USB for `putchar()`
- has a user-accessible button besides the reset button

688dd81400 machine/stm32f103xx: allow board specific UART usage 
Motivation: The bluepill uses USART1 as UART0 but other boards like the
STM32 Nucleo boards (and disco as well) use USART2 for USB COM port.

To avoid duplication of code the same pattern as in `machine_atsamd21.go`
is applied where only UART-specific code is moved to `board_*.go`.

500ee8067d machine/stm32f103xx: fix SPI frequency selection 
The SPI frequency is broken since b8c326d710
added I2C interface and changed the unrelated `PCLK2 = HCLK/4` initialization
to `PCLK2 = HCLK/1` (but I2C uses PCLK1 anyways).

This commit changes all baud rate prescalers to be /4 compared to before.

Note: it is not possible to find an equivalent for 125 KHz SPI speed,
it will be too fast (`f = 72 MHz / 256`)

4ecd478d82 machine: add generic board support on non-baremetal hardware 
Instead of trying to modify periperhals directly, external functions are
called. For example, __tinygo_gpio_set sets a GPIO pin to a specified
value (high or low). It is expected that binaries made this way will be
linked with some extra libraries that implement support for these
functions.

One particularly interesting case is this experimental board simulator:
https://github.com/aykevl/tinygo-play
Compiling code to WebAssembly with the correct build tag for a board
will enable this board to be simulated in the browser.

Atmel/Microchip based SAMD boards are not currently supported, because
their I2C/SPI support is somewhat uncommon and harder to support in the
machine API. They may require a modification to the machine API for
proper support.
